DESIGN CHARTS FOR ONE- AND TWO-STRUT SUPERCAVITATING HYDROFOIL WINGS (WING SERIES A)
Abstract
A set of design charts entitled Wing Series A, for use in the preliminary design of supercavitating or fully ventilated wing systems, is presented. Curves are given relating to the performance of both single-strut and two-strut wings. Series A wings are of tapered planform with zero sweep and zero dihedral. The two strut series A wings are confined to a 2:1 taper ratio, a constant non-dimensional section modulus throughout wing and struts and by the provision that the struts be of parabolic cross section with a fully vented, blunt base. The single-strut series A wings are confined to taper ratios between 1 1/2:1 and 3 1/2:1 and may be specified to have either constant nondimensional section modulus or constant bending stress. Their strut configuration is arbitrary. The format of the design charts is such that, given values of speed and nominal maximum bending stress, it is possible to obtain approximate optimum values of lift coefficient, bending modulu , aspect ratio and lift-drag ratio. Working examples of chart use are also included. (Author)
